Assume that A vector a of length ||a|| =3 units. In addition, a points in a direction that is 135° counterclockwise from the positive x-axis, and a vector b in the xy-plane has a length ||b|| =1/3 and points in the positive y-direction.
a.) Find a.b
b.) calculate the distance between the point(-1,3) and the line 2x - 2y-5=0
